your mandarin does not have ich, it is more likely to be sand in it's mucus covering. everything else needs to be hypoed.
Where do you get $30 for a QT tank? I got lucky and got a 20 gal tank at the ***** sale for $20 (normally $40). The cheapest pump you can find for a 20 gal. is $20. A heater to keep the temp constant, another $15 minimum. Since the fish/fishes have to be in the QT for at least 6 weeks, you need a light, another $25 - $30. Unless you already have that stuff around, you're looking at spending at least $100. Then after the QT is complete, you have two tanks to maintain.
My new Tang has picked up ich, and I'm trying the organic Ich Attack to see if it will get rid of it. Yes, I've read the multiple threads about how this stuff isn't proven, and supposedly won't kill the ich in my DT. After three days of the treatment, all the spots on the Tang are gone. I'm supposed to continue the treatment for at least a week to insure it doesn't come back. So has it gotten rid of the ich in my DT? Who knows? If it does come back, is it because I didn't keep my fish out of my tank for 6 weeks, or because another new livestock (fish, coral, LS, LR) I buy two months later brought it in? I've also read the debates about how ich is always present in a tank, and a breakout occurs due to stress on the fish. Bottom line, unless you have a fully established tank where you are not adding any new fish, coral, LS, or LR, your DT can be susceptible to ich or any other disease. People here will argue that if you QT all your new livestock for 3 weeks, you can keep diseases out of your DT. However, I've read that corals can harbor ich. How do you know a coral has ich? It's won't have spots, or move around the tank 'scratching' itself. So unless I QT a new coral for at least 6 weeks (the time it takes to kill off ich), instead of the standard QT time of 3 weeks, I could easily be introducing ich into my DT. In an enclosed ecosystem like a saltwater aquarium, diseases are inevitable. You can QT all you want, but you can't be 100% sure that new species you add isn't harboring some dormant disease.
